• Barometric pressure effects on the O

sensor: The output from the O

sensor has pressure effects of <0.1% change of output per % change in pressure. When the barometric

pressure changes by ±20% the output from the O

sensorchanges<±0.4%Vol.However,theoxygensensorshowstransientbehaviorwhensubjectedtoarapidchangein
